1. Using the data in the table above, draw the Lorenz curve for 1958. (Note: The "top 5 percent" are part of the "highest quintile." So, in 1994, families with incomes between the 80th and 95th percentiles received 26.8% of total income (46.9 - 20.1 = 26.8).)

 

2. Which year do you expect had the highest Gini index and which do you expect had the lowest? Remember: a low Gini index indicates greater income equality.
